How could an empty tank not be an issue? For those of you with fi cars you should never romp on them with low fuel. I recommend at least 1/4 tank.

Because its not empty! JK I was just under the assumption it was missing during idle. (First Start Up) If that was the case. It will be highly unlikely for it to missed fire. It would be another issue.

I would agree not to be below 1/4 of a tank when FI.

I assumed it was under load. I re-read the thread and that isn't specified

If it is missing at idle you need to check the basics: air, fuel, spark. Swap around coils, compression test, swap around injectors.

There are 2 water temp sensors on the M54: Cylinder head, and coolant outlet at the radiator. The one on the cylinder head is used to run the EMS adaptations, and also the thermostat switching. The one at the radiator runs the fan.....I've only ever seen temps from the cylinder head sensor....and I'm not sure if most monitoring software even looks at the radiator temp sensor.

Edit: Here's what I was able to monitor in 2009...looks like I was watching both. Note the temp range available as well:

One good piece of info is that the radiator fan is controlled by a solid state relay that is mounted onto the fan assembly. (Thats the black blow a the top) This means you can use a low level switching signal to control the fan if you want externally.

Well its done with the exception of the Power steering. Right now I am using the M3 Pressure plate with the stock clutch and it seems to be holding fine(car hasn't seen full boot though). I have a new clutchnet Kevlar clutch but I won't put it in unless I need to.
